Description

  The present invention relates to a POS system. In particular, the present invention relates to a POS system that is reliably performed by an operator who operates the POS system.

  At present, a fingerprint reader is connected to the POS terminal to confirm the identity of the operator of the POS terminal, and the CPU of the POS terminal registers in advance with fingerprint data (so-called biometric data) read by the fingerprint reader. A technique for collating whether or not fingerprint data of a certain person matches is known (for example, see Patent Document 1).

JP 2007-80193 A

  However, when the above technique is applied, although the purpose of identity verification can be achieved, there is a problem that the load on the CPU of the POS terminal increases. In recent years, POS terminals have increased CPU load such as an increase in data amount due to LAN connection, screen display equipment adoption, or customer management processing. However, when the above technology is applied, the POS terminal has an image called fingerprint data. This is because data matching judgment processing is further added. Therefore, when the above technique is applied, there is a problem that the operation of the POS terminal may be temporarily stopped. For example, if there is a pause when the checkout process should be performed as early as possible, such as in the evening, the operational impact will be significant.

  In addition, when the operator who has been temporarily away from the POS terminal 20 returns to the POS terminal 20, a state in which general operations (operations related to checkout such as product registration and checkout) are temporarily prohibited (hereinafter, “ There is a request to quickly return to a state in which a general operation is permitted (hereinafter referred to as a “registration open state”) from a “registration off state”.

  In addition, the operator forgets what kind of biometric data is the registered biometric data of the registered person (for example, which finger is the fingerprint data of which hand) There is also a problem that the authentication process is repeated over and over, which takes time.

  In addition, even if the person is the person himself / herself, there is a case where the person is mistakenly identified as another person by biometric authentication. The operation of the POS terminal is often changed by several people depending on the part, etc., and there is a problem that the purchaser (customer) waits until the authentication is correctly performed if a misidentification occurs every time the change is made. The coincidence determination criterion between the registered biometric data and the read biometric data is not 100% data coincidence. For example, in vein authentication, in the case of anemia, the details of the biometric data are missing or the time of the living body itself is deteriorated. Although changes are taken into account, if the matching criterion is too low, it may be impossible to discriminate against others.

  The present invention has been made in consideration of such circumstances, and provides a technique for smoothly processing the entire POS system when performing biometric authentication in the POS system.

In order to solve the above problems, a POS system according to one aspect of the present invention includes a POS terminal that accepts operations related to product registration and settlement when a cash register is open, and an authentication device that authenticates a handler of the POS terminal. The POS terminal includes a storage means for storing the biometric data of the operator as registered biometric data for each operator number, and the operator number input at the time of the operation for setting the cashier open. When a transmitting means for transmitting the corresponding registered biometric data to the authentication device and a determination result indicating that the biometric data read by the authentication device matches the registered biometric data are acquired from the authentication device, the cash register is opened. The authentication device reads the biometric data from the living body, and reads the biometric data and the POS terminal. Determining whether the al acquired registration biometric data matches, and having a matching determination means for transmitting the determination result to the POS terminal.
According to the POS system, since the CPU of the POS terminal does not perform a heavy load process of biometric data matching determination, the entire process of the POS system that performs biometric authentication can be performed smoothly. In addition, it is possible to perform biometric authentication in the POS system without causing the POS terminal to implement a process that requires specialized technology of biometric data matching determination. Moreover, since the POS terminal stores the registered biometric data for each handler number and transmits the registered biometric data corresponding to the input handler number to the authentication device, there are a plurality of handlers as authentication targets. Even if it exists, it can be applied without problems.

In the POS system, the transmitting unit of the POS terminal may transmit a read preparation command for causing the authentication device to prepare for reading biometric data when transmitting the registered biometric data.
According to the POS system, when the registered biometric data is transmitted to the authentication device, the reading preparation instruction is transmitted to the authentication device, so that the power consumption of the authentication device can be suppressed. In addition, the operator can perform reading by simply placing a predetermined position of the living body on the authentication device 30 without requiring any special operation in the authentication device.

In the POS system, when the POS terminal is in a registration-off state in which operations related to product registration and settlement are temporarily prohibited, the authentication device is set in a reading preparation state in which biometric data can be read. May be.
According to the POS system, when the POS terminal is in the registration-off state, the authentication device is in the reading preparation state. Therefore, when the operator returns from the registration-off state to the registration-open state, the predetermined position of the living body is authenticated. It is only necessary to position it at the position, and it is possible to easily return it.

In the POS system, the POS terminal further includes guide means for outputting the position of the living body to be read as guide information, and the storage means of the POS terminal stores the position data of the living body to be read from the living body for each operator number. And the guidance means of the POS terminal may output the position data corresponding to the operator number input at the time of an operation for setting the cashier open.
According to the POS system, when the operator inputs the operator number to make the cashier open, the position of the living body corresponding to the operator number is displayed. Even if the position of the living body to be read is forgotten, the position of the living body to be read can be confirmed. Therefore, the authentication process does not need to be performed again and again, so that it does not take time for authentication.

In the POS system, the storage unit of the POS terminal stores a matching criterion for the determination by the authentication device for each handler number, and the transmission unit of the POS terminal is in a cash register open state. Together with the registered biometric data corresponding to the handler number input at the time of the operation for performing the match determination criteria corresponding to the handler number to the authentication device, the match determination means of the authentication device is the match determination You may make it perform the said judgment based on a reference | standard.
According to the POS system, it is possible to manage the coincidence determination standard for each operator. Therefore, it is sufficient to reduce the coincidence determination standard only to operators who need to lower the coincidence determination standard to prevent misidentification, Compared with the case where the matching criterion is lowered uniformly, the number of operators who lower the matching criterion can be reduced. In other words, the stability of ecological characteristics varies among individuals, but the matching criteria can be flexibly set and changed for each individual according to the individual differences.

In the POS system, the storage unit of the POS terminal stores, for each handler number, refusal data defining refusal of various operations of the POS terminal, and further, a reference according to the refusal data, The coincidence criterion for the determination by the authentication device is stored, and the transmission unit of the POS terminal stores the handling biometric data together with the registered biometric data corresponding to the operator number input at the time of the operation for setting the cashier open. The coincidence determination criterion corresponding to the rejection data corresponding to the identification number is transmitted to the authentication device, and the coincidence determination unit of the authentication device executes the determination based on the coincidence determination criterion corresponding to the rejection data You may do it.
According to the POS system, since the authentication device performs the matching determination based on the matching determination standard corresponding to the refusal data for each operator, it is possible to realize flexible authentication according to the authority of the operator. become. For example, an operator who has a small responsibility can realize authentication that sets a matching criterion that is less misidentified than an operator who has a large responsibility.

In the POS system, if the match determination means of the authentication device is that the determination does not match, the biometric data is read again to further determine the match, and the guidance means of the POS terminal includes the authentication device An error is output when a determination result indicating that there is no match is obtained, and guidance information for requesting input of a handler number is output when the determination result indicating that there is no match is acquired continuously a predetermined number of times. You may do it.
According to the POS system, it is possible to quickly match when the reading position is not appropriate.

  According to the present invention, when biometric authentication is performed in the POS system, the entire POS system can be processed smoothly.

It is an example of the system block diagram of the POS system by embodiment of this invention. It is an example of the block diagram of the POS terminal of FIG. It is an example of the information memorize | stored in the POS terminal of FIG. 3 is a flowchart showing an example of the operation of the POS terminal of FIG. It is an example of the information displayed on the POS terminal of FIG.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a system configuration diagram of a POS system according to an embodiment of the present invention.

  The POS system 1 according to the embodiment of the present invention is installed in a restaurant or a retail store. As shown in FIG. 1, the POS system 1 includes a server 10, a plurality of POS terminals 20, and a plurality of authentication devices.

  The server 10 collects and manages various files and sales results, and also manages the LAN connected to each POS terminal 20. The connection between the server 10 and each POS terminal 20 may be wired or wireless.

  The POS terminal 20 is a device for registering and paying for products purchased by customers, and includes various operation keys and a display unit. For example, the operator uses the POS terminal 20 to read the barcode of the product or press the preset key to register the product and settle the price for the total price.

  The recognition device 30 is a finger vein recognition device (a general-purpose commercially available device may be used). The recognition device 30 is connected to the POS terminal 20 by, for example, RS232-C, and operates according to a command (hereinafter also referred to as a command) from the POS terminal 20. For example, when the recognition device 30 acquires from the POS terminal 20 a command to prepare for reading biometric data (hereinafter referred to as “preparation command”), the recognition device 30 turns on (emits) a light source for reading the biometric data. .

  FIG. 2 is a block diagram of the POS terminal 20. In FIG. 2, a CPU 201 is a central processing unit, and controls the operation of the POS terminal 20 by reading and executing a program (for example, a program for executing the processing shown in FIG. 4) stored in the ROM 202. To do. The CPU 201 reads and writes various data stored in the RAM 203. The ROM 202 is a read-only memory that stores programs. The RAM 203 is a read / write memory as needed to store a handler file, a biological file, an operation authority file, various messages (for example, error messages), and the like.

  The display unit 204 displays individual product names and prices of products whose barcodes have been read by a scanner unit (not shown), a list and total price of all products that have been read, the number of purchases, a menu screen, various messages, and the like. The operation unit 205 includes various operation keys. The display unit 204 and the operation unit 205 may be implemented as a liquid crystal touch panel.

  The communication unit 206 controls data communication performed with the server 10. The serial I / F 207 controls data communication performed with the authentication device 30. For example, the POS terminal 20 receives biometric data as registration generation data from the authentication device 30 via the serial I / F 207 and transmits the biometric data to the server 10 via the communication unit 206.

FIG. 3 is an example of information stored in the RAM 203 of the POS terminal 20. The handler file is a file that stores data related to the handler (hereinafter referred to as “handler data”). The handler data includes items (columns) such as a handler number, a name, a sales record, a biometric data number, a biometric position, and a coincidence criterion as shown in FIG.
The operator number is identification information for identifying the operator and is a key item of the operator file.
The biometric data number is identification information for identifying biometric data, and stores one or two or more values. For example, in the handler file in the example of FIG. 3A, two biometric data numbers “001” and “002” are separated by a delimiter code (comma) as the biometric data number related to the handler number “2001”. Is remembered.
The living body position is information indicating the position (part) of the living body, and stores one or two or more values corresponding to the biological data number. For example, in the handler file in the example of FIG. 3A, the biological position “left finger” corresponding to the biological data number “001” and the biological data number “002” are associated with the biological number related to the handler number “2001”. The biological position “middle right” corresponding to “is stored by being separated by a delimiter code (comma).
The match determination criterion is information that is referred to when comparing the biometric data read by the authentication device 30 with the registered biometric data to determine whether or not they match. For example, the coincidence determination criterion “1” indicates that a match is not determined unless the degree of coincidence of the two data is equal to or greater than a predetermined value close to 100%. Even if the degree of coincidence of both data is small, it is easily determined that they coincide.

The biometric file is a file that stores a biometric data number and registered biometric data, for example, as shown in FIG.
The biometric data number is identification information for identifying biometric data as described above, and is a key item of a biometric file. The registered biometric data is biometric data read by the recognition device 30 and is set as registered biometric data.
The biometric data registration procedure, that is, the registration biometric data storage procedure will be described below. The POS terminal 20 receives biometric data (biometric data to be registered biometric data) from the authentication device 30 after the setting of the biometric file is selected from the menu screen. The POS terminal 20 transmits the received biological data to the server 10 together with the operator number, the generated data number, and the biological position. The server 10 distributes the biometric data together with the operator number, the biometric data number, and the biometric position to all the POS terminals 20 (or the POS terminals 20 other than the POS terminal 20 that has received the biometric data from the authentication device 30). Thereby, all the POS terminals 20 can hold the same and latest handler file and biometric file. The operator number and biometric position that the POS terminal 20 transmits to the server 10 together with the biometric data are input on the menu screen, for example. In addition, the biometric data number transmitted from the POS terminal 20 to the server 10 together with the biometric data is automatically assigned when an operator number or the like is input on the menu screen.
The POS terminal 20 that has received the biometric data from the authentication device 30 updates the handler file and biometric file stored therein, and transmits the updated handler file and biometric file to the server 10. The updated handler file and biometric file may be distributed.

The operation authority file is a file that stores data related to the operation authority of the operator (hereinafter referred to as “operation authority data”). For example, as shown in FIG. 3C, the operation authority data includes items such as operator number, scan registration, lock key, selling price change, and file setting.
As described above, the operator number is identification information for identifying the operator, and is a key item of the operation authority file. The scan registration, the closing key, the selling price change, and the file setting store information (also referred to as permission / denial data) indicating operation permission / inhibition of each operation.
In the operation authority file in the example of FIG. 3C, the operation authority is set stronger (responsible) as the operator number is larger. For example, the operator with the operator number “2001” is permitted only to perform the scan registration operation, and the operator with the operator number “9001” is permitted to perform any operation of scan registration, lock key, selling price change, and file setting. The effect is set.

  FIG. 4 is a flowchart showing an example of the operation of the POS terminal 20. FIG. 5 is an example of information displayed on the POS terminal 20. The operation of the POS terminal 20 will be described below using the flowchart shown in FIG. This flowchart starts when the POS terminal 20 is turned on. At the start of this flowchart, it is assumed that the POS terminal 20 stores information necessary for operations such as various files shown in FIG. 3 and reading retry count setting information, for example. The same applies to the authentication device 30.

  In FIG. 4, the POS terminal 20 determines whether or not the operator number has been input via the screen for inputting the operator number for opening the cash register (step S1). If the POS terminal 20 determines that the operator number has not been input (step S1: No), it repeats step S1 until it determines that the operator number has been input.

  If the POS terminal 20 determines that the operator number has been input (step S1: Yes), it reads the operator data of the input operator number from the operator file stored in the RAM 203 (step S2). Next, the POS terminal 20 displays an authentication guidance display including the living body position included in the read operator data on the display unit 204 (step S3). For example, when the POS terminal 20 determines that the operator number “9001” has been input, the operator data of the operator number “9001” is read from the operator file shown in FIG. An authentication guidance display as shown in FIG. 5 including the biological position “middle right” included in the data is displayed on the display unit 204.

  Next, the POS terminal 20 transmits a command for causing the authentication device 30 to prepare for reading biometric data, that is, a preparation command (step S4). Specifically, the POS terminal 20 transmits a command for turning on a light source for reading biometric data to the authentication device 30 as a preparation command. As a result, the authentication device 30 turns on the light source for reading the biometric data.

  Next, the POS terminal 20 reads out registered biometric data corresponding to the entered operator number from the biometric file stored in the RAM 203 (step S5). Next, the POS terminal 20 transmits the read registered biometric data to the authentication device together with the coincidence determination criterion included in the handler data read in step S2 (step S6). For example, when the handler number “9001” is input, the POS terminal 20 reads the registered biometric data associated with the biometric data number “351” included in the handler data read in step S2, and then in step S2. The coincidence criterion “1” included in the read handler data is transmitted to the authentication device 30.

  Next, the POS terminal 20 determines whether a determination result indicating that the registered biometric data transmitted to the authentication device 30 in step S6 matches the biometric data read by the authentication device 30 is received from the authentication device 30 ( Step S7). Note that the authentication device 30 determines whether the read biometric data matches the registered biometric data received from the POS terminal 20 in step S6 based on the match determination criterion received from the POS terminal 20 in step S6. The determination result is transmitted to the POS terminal 20.

  If the POS terminal 20 determines that it has not received the determination result indicating that it matches from the authentication device 30 (step S7: No), it displays an error (for example, an error indicating that the operator number must be entered again). (Step S8), a command for canceling the preparation for reading biometric data (hereinafter referred to as “preparation cancellation command”) is transmitted to the authentication device 30 (Step S9). Specifically, the POS terminal 20 transmits a command for turning off the light source to the authentication device 30 as a preparation cancellation command. Then, the process returns to step S1.

  If the POS terminal 20 determines that the matching result is received from the authentication device 30 (step S7: Yes), the POS terminal 20 transmits a preparation release command to the authentication device 30 (step S10).

  Next, the POS terminal 20 shifts to a state in which general operations (operations related to checkout such as product registration and checkout) are permitted, that is, a cash register open state (step S11). In the cash register open state, the POS terminal 20 executes general processing (processing related to checkout such as product registration and checkout) based on an operation by the operator (step S12). The range that can be operated in the cash register open state is based on the operation authority file. For example, when the operator number “9001” is input, the POS terminal 20 reads the operation authority data of the operator number “9000 to 9999” from the operation authority file shown in FIG. Allows operation of key, selling price change and file setting.

  The POS terminal 20 determines whether or not an operation for temporarily prohibiting a general operation, that is, an operation for shifting to a registration-off state has been received (step S13). When the POS terminal 20 determines that an operation for shifting to the registration-off state has been received (step S13: Yes), the POS terminal 20 shifts to the registration-off state (step S14). In the cash-off state, the POS terminal 20 transmits a preparation command to the authentication device 30 (step S15).

  Next, the POS terminal 20 determines whether or not a determination result indicating that the registered biometric data matches the biometric data read by the authentication device 30 is received from the authentication device 30 (step S16).

  If the POS terminal 20 determines that it does not receive the determination result indicating that they match from the authentication device 30 (step S16: No), it returns to step S16. If the POS terminal 20 determines that the matching result is received from the authentication device 30 (step S16: Yes), the process returns to step S10.

  If the POS terminal 20 determines that an operation for shifting to the registration-off state has not been received (step S13: No), an operation for ending the processing by the POS terminal 20 (hereinafter referred to as a “close operation”) is received. It is determined whether or not (step S17). The close operation is performed, for example, at the end of a day's work.

  When the POS terminal 20 determines that the close operation has not been received (step S17: No), the POS terminal 20 returns to step S12. When the POS terminal 20 determines that the close operation has been accepted (step S17: Yes), as the cash register close process, the processing result during the cash register open is determined and a report is output, and the operation shifts to the operation prohibited state (step S18). . For example, as the cash register closing process, the POS terminal 20 determines the processing results while the cash register is open, and outputs a report summarizing the processing results including the input cash amount when the operator inputs the cash amount. To do. Then, this flowchart ends.

  As described above, according to the embodiment described above, when performing biometric authentication in the POS system 1, the CPU of the POS terminal 20 does not perform a heavy load process of biometric data matching determination. You can do it smoothly. In addition, the biometric authentication can be performed in the POS system 1 without causing the POS terminal 20 to implement a process requiring specialized technology of biometric data matching determination. Moreover, since the POS terminal 20 stores the registered biometric data for each operator number and transmits the registered biometric data corresponding to the input operator number to the authentication device 30, there are a plurality of operators as authentication targets. Even in cases, it can be applied without problems.

  Further, since the POS terminal 20 transmits a preparation command to the authentication device 30 when transmitting the registered biometric data to the authentication device 30, the power consumption of the authentication device 30 can be suppressed. In addition, the operator can perform reading by simply placing a predetermined position of the living body on the authentication device 30 without requiring any special operation in the authentication device 30.

  Further, in the flowchart of FIG. 7, the POS terminal 20 shifts to the registration-off state (step S14), and then transmits a preparation command to the authentication device 30 (step S15), that is, the POS terminal 20 is in the registration-off state. At this time, since the authentication device 30 is in the reading ready state, when the operator returns from the registration-off state to the registration-open state, the operator only has to place the predetermined position of the living body on the authentication device, and can easily return. To be able to.

  Further, in the POS terminal 20, when the operator inputs the operator number in order to set the cashier open, the position (part) of the living body corresponding to the operator number is displayed. At this time, even if the position of the living body to be read is forgotten, the position of the living body to be read can be confirmed. Therefore, the authentication process does not need to be performed again and again, so that it does not take time for authentication.

  Since the matching criteria can be managed for each operator, the matching criteria should be lowered only for those who need to lower the matching criteria to prevent misidentification, and the matching criteria will be lowered uniformly. Compared to the case, it is possible to reduce the number of operators who lower the matching criterion. In other words, the stability of ecological characteristics varies among individuals, but the matching criteria can be flexibly set and changed for each individual according to the individual differences.

  In the above-described embodiment, the POS terminal 20 stores the coincidence determination criterion for each operator as shown in FIG. 3A and transmits the coincidence determination criterion corresponding to the input operator number. As shown in FIG. 3 (d), the operation authority data, that is, the coincidence determination standard according to the permission / denial data for each operator is stored, and the coincidence determination standard according to the rejection data corresponding to the input operator number is stored. You may make it transmit. As a result, the authentication device 30 performs the matching determination based on the matching determination criterion corresponding to the rejection data for each operator, so that flexible authentication according to the authority of the operator can be realized. For example, an operator who has a small responsibility can realize authentication that sets a matching criterion that is less misidentified than an operator who has a large responsibility.

  In the above-described embodiment, the POS terminal 20 transmits the match determination standard to the authentication device 30 every time authentication is performed, but the POS terminal 20 authenticates the match determination standard except when the match determination standard is changed. It is not necessary to transmit to the authentication device 30 each time. That is, the authentication device 30 stores the match determination criteria for each operator (or match determination criteria according to permission / denial data) acquired from the POS terminal 20 and determines a match based on the stored match determination criteria. Good.

  In the above embodiment, the authentication device 30 turns on the light source for reading the biometric data when the preparation command is acquired. However, when the preparation command is acquired, the authentication device 30 may shift from the sleep mode to the standby mode. . For example, the POS terminal 20 may separately transmit a command for causing the authentication device 30 to shift from a sleep mode to a standby mode and a command for turning on a light source for reading biometric data to the authentication device 30 separately. Then, a command for causing the authentication device 30 to shift from the sleep mode to the standby mode may be transmitted to the authentication device 30, and the authentication device 30 may detect the presence or absence of a finger and turn on the light source.

  Moreover, in the said embodiment, as shown in the flowchart of FIG. 7, when it is judged that the process flow of the POS terminal 20 has not received the judgment result that it corresponds from the authentication apparatus 30 (step S7: No), An error (for example, an error indicating that the operator number should be entered again from the input of the operator number) is displayed (step S8), a preparation cancellation command is transmitted to the authentication device 30 (step S9), and the process returns to step S1. The processing flow of processing is not limited to this. For example, if the POS terminal 20 determines that the determination result indicating that they do not match is received from the authentication device 30 (step S7: No), the POS terminal 20 does not transmit the preparation release command to the authentication device 30 and indicates that the position is incorrect. When the process of displaying the error and returning to step S7 is repeated a predetermined number of times, and after repeating the above process a predetermined number of times, it is further determined that a determination result indicating that they do not match is received from the authentication device 30 (step S7: No). An error indicating that it is necessary to start over from the input of the operator number may be displayed (step S8), a preparation cancellation command may be transmitted to the authentication device 30 (step S9), and the process may return to step S1. This makes it possible to quickly match when the reading position is not appropriate. For example, when the position and angle of the living body are inaccurate in the authentication for the person himself / herself, it is not necessary to input the operator number again, so that the operability of the operation related to the authentication process is improved.

  In the above embodiment, as described above, when the POS terminal 20 is in the registration-off state, the authentication device 30 is in the reading preparation state. However, after the operator number is input, the authentication device 30 is in the reading preparation state. It may be. For example, the POS terminal 20 may shift to the registration off state (step S14) and return to step S1. As a result, it becomes possible to authenticate a handler other than the one who is temporarily away from the POS terminal 20. However, this embodiment is superior when the operator who is temporarily away from the POS terminal 20 is quickly authenticated.

  Moreover, in the said embodiment, although the operator number was input at the time of cash register opening operation, you may abbreviate | omit input of an operator number. For example, the authentication device 30 can read the biometric data without inputting the operator number to the POS terminal 20, and the authentication device 30 reads the biometric data as shown in FIG. Files necessary for matching determination such as a person file and a biometric file can be referred to, and the authentication apparatus 30 can read the biometric data based on any registered biometric data and a matching determination criterion corresponding to the registered biometric data. When it is determined that they match, a determination result indicating that they match may be transmitted to the POS terminal 20 together with the operator number corresponding to the registered biometric data. In addition, as a method for the authentication device 30 to read the biometric data without inputting the operator number, for example, when the operator performs a predetermined simple operation (for example, pressing a predetermined button) on the POS terminal 20, the POS is performed. The terminal 20 may transmit a preparation command to the authentication device 30. When the operator directly performs a predetermined simple operation on the authentication device 30, the authentication device 30 turns on the light source. Also good.

  In the above embodiment, the example of the finger vein is described as the biometric data, but it may be a fingerprint, a hand vein, an iris, or the like.

  The POS system 1 in the present embodiment includes a number of inventions. Therefore, the biometric authentication match determination is not limited to the mode executed by the authentication device 30, and the authentication device 30 (that is, a biometric data reading device) reads the biometric data and transmits it to the POS terminal 20 or the server 10, and the POS terminal. 20 or the server 10 may execute the matching determination. In addition, when the server 10 performs a coincidence determination, the server 10 may acquire various kinds of information (information shown in FIG. 3) necessary for authentication from the POS terminal 20 or may be stored by the server 10 itself. Good.
